so(10) — real Lie algebra
The real skew-symmetric 10 × 10 matrices with commutator bracket.
Reference coverageCompact algebraSimple over R
Reference properties
From algebra to group
The linked groups integrate this real Lie algebra. They can have different centers and fundamental groups, so their ordinary representations are not interchangeable solely because their Lie algebras agree. [sources]
